My hobbies
My motto is "live to ride, ride to live". No, I dont drive a HD. I like a
speed and fast curves. I like to ride on track. I'm not a race driver, track
racing is only fun for me. But of cource I try to do new laprecord's every
year.
I drive on Alastaro's race circuit (Kawasaki zx-9r -01)
I have a behind about 32 000 kilometers on motorcycle. I have been drive
about 3000 kilometer about on track. It mean about 20 days on track and about
10 track day on years.

BMS / CCS
Shortly: BMS mean a Battery Management System. CCS is name for Finnish
Electric Vehicles Technologies battery management system: Cell Control System.
They do a tactical move to brand a new name for their own system. This is
because BMS is a universal term for all battery monitoring system. This mean
that BMS do nothing smart as balansing. It is only a stupid protection circuit.
Its only watch over and under voltages and overtemperature.They want tell you
that they have something better.
eNode is part of eBMS-project.
Node is a BMS-component which read a cell voltage and cell temperature. Its
also have a Power electronic which using a balancing lithium batteries. It is
usual a isolated dc-dc which can boost a invidivially every cell. We are design
own non commersial node to free using.
eNodes's paper model over TS's LFP-40 cell:
eNode on top:
eNode's specs:
Balancing be based to Ah.
Active balansing system (boost)
Atmega32-prosessor
Isolated Can-bus
Input:
CAN-bus
30-90Vdc-bus for DC-DC (boost)
12Vdc-bus for electronic
Output:
Can-bus
Isolated boost
Read a cell voltage (0-5V)
Read a cell temperature
Effectiveness:
Boost Power is overkill for 40 ah LFP-cell and good for 400 ah
LFP-cell. But it is much cheapen to do only one model =)

We have get a first three eNode proto cards. First test is completed. We must a fix some filtering. Now we can start a program atmega32. That is very big step for our eNode development.
